Tha iiliaiik 29.0!

A cross picco 31, which' l hav. shown as consisting iuai'oly of ii picco of i :tout wirt` `with thi` c'nils honfovei', ia ut through mindering" holas v3i! 33, dri ed 05 thc chain suction l5 into 'wiiici thc hoolwd i `traiisvoifsi"ly throughlhu grato iar or ita rib formed directly 13 and the shank 28 of the shoe, to retain said shoe against escape from its socket. I t will thus he seen that. the grate liar, or its end l2, is securely attached to the chain 25.

' /tt the saine time, the attachment of said end lwitlizthe travel oft e chain upon its spmcket wheels or rollers, because of the detail construction next to be described.Y The head 20 of the slice 30 provides iitopposite sides of the shank 28, e-r toward the o poaite aides of the chain, shoulders 34 34 or the tlatwise link 26 torest. ii in, an at each of its other two o posite si es', or sides facing lengthwise olf) the chain, the shank has checks 35, 35 adapted to tit against the end of the adjacent vertical lilik 261 and forming a rounded seat therefor. The head 29 is also recessed, as at 36, to form a continuation of said se'atfor the end of the ad'acent vertical link, said recess being suitab y curved to lit the link, as shown in Fig. 3. Furthermore, the opposite lower edges of the rib 13 may be recessed as nt 37, 37, if necessa or desirable to receive the upper parts of ty e vertical links 261 and form curved seats therefor, as shown in Fig. 3 also. alinement transversely of the te bar with the socket 27, and the hole 32' or the pin 31 is drilled through the rib -13 between `said seats and the body part of the grate bar so as to clear the seats. lly my inventionthere fore, the end l2 of the te bar is attached to the conveying chain 5 by simply resting.

it upon a flatw-ise link and then passing the fastening shoe 30 through said atwise link from its side away from the bar, the shank of said shoe entering the socket 2T in the bar, and the cross pin 31 when put in place locks the whole together. There is thus a minimum of parts and of operations, and furthermore the grate bars are held firmly in position on the chains. 'Es hilly do the curved seats on the head o the listening shoe, facing lengthwise of the chains and iit the opposite side thereof from the griitebars, serve to pi'event'any tipping over or tilting of the bars.' Se also (o the curved seats on 'the grate bars and engagging the adjacent side of the chains pre- `lili vent any looseni'ss iff each liiir with respectI to its lilik, and particularly when in combi? nationl willi the other curved seats just men# v tioncd.

While the links of the eliiiiii'miist move freely on one another for the usual undulating motion of lthisclass of chain grates, it is also necessiti' for the same purpose :that

cach bar be ri 'id enough willi respect to its link so that t ie motion is not lost between These curved seats are in substantiall .said chain, said nien msnm l the chain and here. This result my im proved connecting shoe secures to a marked I claim icl. llie combination with a chain, and a transverse member at one side thereof, of a fastening shoe formin at one end portion of itself a shank whic will inserted in a link, means securing the en of said shank to the said transverse member, and a head at the other end kof the shoe havin in opposite sides o! itself curved seats fl ing tie ends of adjacent links at the opposite alle ot the chain from the transverse meinl'. 2. The combination with a chain, and a transverse member at one side thereof, of a fastenin shoe formin at one end of itsel a shank whic will pass t in a link, means securing the en of said shank to the said transverse member, and a head at the other end of the shoe lying at the opposite side of the chi in from the transverse member said head having at'ita sides facing lengtiwise of the chain eeeta fitting the ends of adacent links and at ita other sides seats fort e arallel the link throu h which e shoe extends.
